In remarks prepared for a Democratic Party dinner Saturday night in Des Moines, Iowa, the New York Democrat says that 2016, in his words, "is Hillary's time."

The former first lady, U.S. senator and secretary of state would be the leading contender for the Democratic nomination if she were to run. She told New York magazine in an article published in September that she was wrestling with whether to undertake another campaign.

Other potential Democratic presidential candidates include Vice President Joe Biden, New York Gov. Andrew Cuomo and Maryland Gov. Martin O'Malley.
